Introducing structural diversity into the nucleoside scaffold for use as potential chemotherapeutics has long been considered an important approach to drug design. In that regard, we have designed and synthesized a number of innovative 2'-deoxy expanded nucleosides where a heteroaromatic thiophene spacer ring has been inserted in between the imidazole and pyrimidine ring systems of the natural purine scaffold. The synthetic efforts towards realizing the expanded 2'-deoxy-guanosine and -adenosine tricyclic analogues as well as the preliminary biological results are presented herein.
将结构多样性引入核苷支架中,将其作为潜在的化疗药物,一直以来都被认为是药物设计的重要方法。在这方面,我们设计并合成了一些创新的 2'-脱氧扩展核苷,其中在天然嘌呤支架的咪唑环和嘧啶环系统之间插入了一个杂芳族噻吩间隔环。本文介绍了实现扩展的 2'-脱氧鸟苷和 -腺苷三环类似物的合成努力以及初步的生物学结果。
